This Guide has been developed for facility owner organizations, along with designers, contractors, operators, and consultants who advise owners. We assume that the reader has a fundamental understanding of BIM concepts. For those readers who are not familiar with BIM, it is recommended, that you review BIM literature such as BIG BIM little bim by Jernigan (2008), the BIM Handbook by Eastman et al. (2011), or other BIM resources from the GSA, US Department of Veterans Affairs, US Army Corp of Engineers, and others. This Guide is not intended to convince an organization to use BIM, but rather how to implement it. If the organization has determined that BIM can add value to the organization, this Guide will lead them through the steps to integrate BIM into the organization. However, if the organization is unsure about implementing BIM, it may be necessary to further research the benefits and risks of BIM to make a business case for implementing BIM.
This BIM Project Execution Planning Guide is a product of the BIM Project Execution Planning Project within the buildingSMART alliance™ (bSa), a council within the National Institute of Building Sciences. The bSa is charged with developing the National Building Information Modeling Standard – United States™ (NBIMS-US). This Guide was developed to provide a practical manual that can be used by project teams to design their BIM strategy and develop a BEP. The core modeling and information exchange concepts have been designed to complement the long-term goals of the bSa in the development of a standard that can be implemented throughout the AECOO Industry to improve the efficiency and effectiveness of BIM implementation on projects.
Students groups use balsa wood and glue to build their own towers using some of the techniques they learned from the associated lesson. While general guidelines are provided, give students freedom with their designs and encourage them to implement what they have learned about structural engineering. The winning team design is the tower with the highest strength-to-weight ratio.
Student teams design their own booms (bridges) and engage in a friendly competition with other teams to test their designs. Each team strives to design a boom that is light, can hold a certain amount of weight, and is affordable to build. Teams are also assessed on how close their design estimations are to the final weight and cost of their boom "construction." This activity teaches students how to simplify the math behind the risk and estimation process that takes place at every engineering firm prior to the bidding phase when an engineering firm calculates how much money it will take to build the project and then "bids" against other competitors.
This timeline includes key bridges and events in bridge engineering, images, links, and project references. It provides easier access for students to a more comprehensive view of bridge history, and how it forms the base of current practice and understanding of bridge analysis and design.
Through a five-lesson series that includes numerous hands-on activities, students are introduced to the importance and pervasiveness of bridges for connecting people to resources, places and other people, with references to many historical and current-day examples. In learning about bridge types arch, beam, truss and suspension students explore the effect of tensile and compressive forces. Students investigate the calculations that go into designing bridges; they learn about loads and cross-sectional areas by designing and testing the strength of model piers. Geology and soils are explored as they discover the importance of foundations, bearing pressure and settlement considerations in the creation of dependable bridges and structures. Students learn about brittle and ductile material properties. Students also learn about the many cost factors that comprise the economic considerations of bridge building. Bridges are unique challenges that take advantage of the creative nature of engineering.
Students are introduced to some basic civil engineering concepts in an exciting and interactive manner. Bridges and skyscrapers, the two most visible structures designed by civil engineers, are discussed in depth, including the design principles behind them. To help students visualize in three dimensions, one hands-on activity presents three-dimensional coordinate systems and gives students practice finding and describing points in space. After learning about skyscrapers, tower design principles and how materials absorb different types of forces, students compete to build their own newspaper towers to meet specific design criteria.The unit concludes with student groups using balsa wood and glue to design and build tower structures to withstand vertical and lateral forces.
In the exploration of ways to use solar energy, students investigate the thermal energy storage capacities of different test materials to determine which to use in passive solar building design.
Students consider the Earth's major types of landforms such as mountains, rivers, plains, hills, canyons, oceans and plateaus. Student teams build three-dimensional models of landscapes, depicting several of these landforms. Once the models are built, they act as civil and transportation engineers to design and build roads through the landscapes they have created. The worksheet is provided in English and Spanish.
Based on working on exercises on project decision making and planning, the specific context of working abroad in general and in developing countries in particular is illustrated, with regard to socio-cultural aspects, planning and financing of projects, roles of (consulting) engineers and contractors, local materials, techniques and knowledge and environmental issues.
Explore the role of national governments, municipalities, companies and the international community in climate change mitigation. Learn to set reduction targets yourself and translate them into action plans.
“Every action matters
Every bit of warming matters
Every year matters
Every choice matters.”
This was the brief summary of a 2018 report of the Intergovernmental Panel on Climate Change (IPCC), the scientific advisory board of the United Nations.
But who should take action?
In earlier courses, we already set out what is needed to limit the impact of climate change. In this course, we will explore the role of national governments, the international community, companies, and sub-national governments, like cities, municipalities, provinces, and regions.
We start from the idea that climate governance is polycentric. None of these parties can mitigate the dangers of climate change all by themselves. Each of these types of organization has its particular strength. If you work – or plan to work – in or with any such organization, then through this course you will learn how to be successful and effective in playing your part in mitigating climate change.
Important elements that will be discussed for the various players in the field are:
What roles can the different organizations play?
How can emission reduction targets be set so that they are both ambitious and feasible?
How can meaningful emission reduction plans be developed that actually result in emission reduction on the ground?
Examples will be presented by professionals who have been successful in their own organization. They are willing to share the failures and critical success factors in their strategies.
What You'll Learn
Understand how international climate agreements work.
Assess the sphere of influence of your own organization.
Learn how to develop national climate policies and evaluate the relevance of existing policies for your organization.
Be able to set ambitious and feasible GHG emission reduction targets for companies and discover how to translate these into a climate action plan.
Design approaches to tackle greenhouse gas emissions in supply chains.
Be able to set ambitious and feasible GHG emission reduction targets for cities and municipalities and learn how to translate these into climate action plans.
Decide in which areas the greatest acceleration of climate action is needed.
Students gain a basic understanding of the properties of media soil, sand, compost, gravel and how these materials affect the movement of water (infiltration/percolation) into and below the surface of the ground. They learn about permeability, porosity, particle size, surface area, capillary action, storage capacity and field capacity, and how the characteristics of the materials that compose the media layer ultimately affect the recharging of groundwater tables. They test each type of material, determining storage capacity, field capacity and infiltration rates, seeing the effect of media size on infiltration rate and storage. Then teams apply the testing results to the design their own material mixes that best meet the design requirements. To conclude, they talk about how engineers apply what students learned in the activity about the infiltration rates of different soil materials to the design of stormwater management systems.
The purpose of this course is to convey knowledge of the various physical processes associated with slurry handling and transport during dredging. This knowledge is needed for the design of dredging equipment and for planning efficient equipment operations. The various processes are discussed and theories and simulation models that describe the processes are presented and compared during the course. The course can be broken down into four elements: 1. Pumps and engines a. Pump characteristics and cavitation b. Influence of particles on pump characteristics. 2. Hydraulic transport in pipelines a. Two-phase (solid-liquid) flow through pipelines b. Newtonian slurries c. Non Newtonian slurries d. Inclined and long pipelines. 3. Pump and pipeline systems a. Operation point and areas b. Production factors. 4. Case studies
This course deals with the design of drinking water treatment plants. We discuss theory and design exercises.
This unit provides the framework for conducting an “engineering design field day” that combines 6 hands-on engineering activities into a culminating school (or multi-school) competition. The activities are a mix of design and problem-solving projects inspired by real-world engineering challenges: kite making, sail cars, tall towers, strong towers and a ball and tools obstacle course. The assortment of events engage children who have varied interests and cover a range of disciplines such as aerospace, mechanical and civil engineering. An optional math test—for each of grades 1-6—is provided as an alternative activity to incorporate into the field day event. Of course, the 6 activities in this unit also are suitable to conduct as standalone activities that are unaffiliated with a big event.

Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical pencil lead than with an eraser. Then they prove why this is so by using the basic equation for stress and applying the concepts to real engineering problems.
Students develop and solidify their understanding of the concept of "perimeter" as they engage in a portion of the civil engineering task of land surveying. Specifically, they measure and calculate the perimeter of a fenced in area of "farmland," and see that this length is equivalent to the minimum required length of a fence to enclose it. Doing this for variously shaped areas confirms that the perimeter is the minimal length of fence required to enclose those shapes. Then students use the technology of a LEGO MINDSTORMS(TM) NXT robot to automate this task. After measuring the perimeter (and thus required fence length) of the "farmland," students see the NXT robot travel around this length, just as a surveyor might travel around an area during the course of surveying land or measuring for fence materials. While practicing their problem solving and measurement skills, students learn and reinforce their scientific and geometric vocabulary.
This book is aimed at undergraduate civil engineering students, though the material may provide a useful review for practitioners and graduate students in transportation. Typically, this would be for an Introduction to Transportation course, which might be taken by most students in their sophomore or junior year. Often this is the first engineering course students take, which requires a switch in thinking from simply solving given problems to formulating the problem mathematically before solving it, i.e. from straight-forward calculation often found in undergraduate Calculus to vaguer word problems more reflective of the real world.
Students are introduced to innovative stormwater management strategies that are being used to restore the hydrology and water quality of urbanized areas to pre-development conditions. Collectively called green infrastructure (GI) and low-impact development (LID) technologies, they include green roofs and vegetative walls, bioretention or rain gardens, bioswales, planter boxes, permeable pavement, urban tree canopy, rainwater harvesting, downspout disconnection, green streets and alleys, and green parking. These approaches differ from the traditional centralized stormwater collection system with the idea of handling stormwater at its sources, resulting in many environmental, economic and societal benefits. A PowerPoint® presentation provides photographic examples, and a companion file gives students the opportunity to sketch in their ideas for using the technologies to make improvements to 10 real-world design scenarios.
